From: Sean Christopherson Date: Fri, 2 Aug 2024 20:01:35 +0000 (-0700) Subject: KVM: Return '0' directly when there's no task to yield to X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=6cf9ef23d9428ca4950a818e3e70bd818748815a;p=linux.git KVM: Return '0' directly when there's no task to yield to Do "return 0" instead of initializing and returning a local variable in kvm_vcpu_yield_to(), e.g. so that it's more obvious what the function returns if there is no task. No functional change intended.
